THlLL-COUPLING.

SPECIFICATION forming part of Letters Patent No. 239,255, dated March22, 1881. Application filed NovemberlB, 1880. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM E. KINNEAR, of Fremont, in the county ofSandusky and State of Ohio, have invented a new and valuable Improvementin Thin-Couplings; and I do hereby declare that the following is a full,clear, and exact description of the construction and operation of thesame, reference being bad to the annexed drawings, making a part of thisspecification, and to the letters and figures of reference markedthereon.

Figure 1 of the drawings isa side view. Fig. 2 is a horizontal section.V

This invention relates to devices for attaching thills and poles tovehicles.

It consists in the construction hereinafter described. In the annexeddrawings, A is the carriageaXle; B, the clip. Projecting in front. fromclip 15 are the ears D I), one of which is integral with said clip, andthe other is attached there-- to by a rule-joint, d. In the ends a ofsaid ears are bored holes E, and on the inside of said ears, back ofholes E, are formed recesses or seats F, one in each ear, the holes andrecesses being opposite each to each when the ears are in position.Seated at the bottom of each recess F is a stud, H, made of hard metal,which is inserted into the ear and made fast therein. I is theshaft-iron, having head K, said head having cuwed ends L L, of a sizeand shape to snugly fit recesses F. In the points of ends L L aredepressions Z l, of a size and shape to snugly fit the projecting innerends of studs with the threads on the bolt.

In connecting the thills or pole to the vehicle, the head K is placedwith its ends L L resting in recesses F F, with the studs H H bearingindepressions Z Z. The bolt M is then run through holes E E, and byturning upon its end the whole is made fast. To compensate for anyslight wear, the bolt M can be tightened up.

In constructing the recesses F F, studs H H, and ends L L, with theirdepressions l l, the aim is to give them such-a shape and fit that thegreater part of the wear will come upon the studs, which act as pintleson which the shaft-iron turns. As these studs become worn they can bereadily backed out and new ones inserted in their place.

What I claim is- The combination of ears D D, one rigid with, the otherhinged to, the clip B, and having holes E E, one being threaded, andrecesses F F, hard-metal studs H H, made fast insaid recesses, head K,having depressions l l in its ends L L, and screw-bolt M, allconstructed and arranged as and for the purpose described.

In testimony that I claim the above I have hereunto subscribed my namein the presence of three witnesses.

WILLIAM ERVIN KINNEAR.
